Not that their first wedding was lacking , he says of his Buenos Aires ceremony , which was sealed with a celebration in a mansion outside the Argentine capital . `` It was a great night -- really , a beautiful night , '' Bublé says . `` Her family is so special and my family is so special that when they came together , we danced 'til 7 a.m. ''

He adds that his wife , who sparkled in a violet dress and silver high heels , `` looked so gorgeous and , ah , we were just saying before the cameras turned on that everyone says , ` Marriage -- nothing changes . Oh , it 's just a piece of paper . ' But I love her more . It 's obviously more serious , and you make some promises that are more important to keep . ''

But the newlywed was n't just gushing about Lopilato , 23 . Fresh off their three week-long honeymoon , he quips , it was time for another vacation -- from each other .

`` If I look like I 'm content , it 's because she 's been in Argentina for a week and I 've been -LSB- in Canada -RSB- , '' he says , with a laugh . `` We love each other so much , we totally need a break . ... By the end -LSB- of the honeymoon -RSB- , you want to kill each other . ''

All kidding aside , `` I 'm happy , '' he says . `` I think she feels the same way , too . ''
